Cаse Study: A Pаinful Wоund Jаkоb, a 20-year-оld instructor at a summer sports camp, scraped his knee while playing basketball. He assumed it was only a minor abrasion that would heal quickly, as many others had before. However, the wound began to resemble an insect bite and became increasingly painful, red, and swollen. A nurse examines the lesion and observes a large amount of pus oozing from the wound. A swab sample is collected and sent to the laboratory for analysis. In the microbiology lab, the technician first observes the specimen using a brightfield microscope. The bacterial cells are nearly transparent and difficult to see. To increase contrast, the technician inserts an opaque light stop above the illuminator. With darkfield microscopy, the cells are much easier to observe. They appear spherical and grouped in grape-like clusters. The technician then performs a Gram stain. Under the brightfield microscope, the stained sample clearly reveals the Gram reaction and cellular arrangement. 1. Based on the Gram stain results, what type of bacterium is this? [color3] What does the arrangement of spherical cells in grape-like clusters suggest? [color6] 2. What kind of cell wall structure does this bacterium have? [color4] 3. What clinical signs is Sam showing? [color1] 4. What symptoms is Sam reporting? [color2] 5. What is the most likely diagnosis of Sam’s skin infection? [color5] 6. Why is the Gram stain often used early in bacterial identification? [color7] 7. What type of treatment would likely be prescribed? [color8]
